Not really sure where to put this, since in over 5 years this is the first time i've had this particular problem.

Following the regular update cycle of Java on Vista I have finally reached a point where jpatch no longer functions after it opens. this started today after the installation of jre6u21. this may just be a bug on this machine but there are no error messages at all so i haven't the faintest clue about what to do

After all of the time I spent enjoying linux---truth, no sarcasm!---that was the first thing I thought of.

No error messages from version 0.4preview1, but no response other than a dead gui either. version 0.5.2 works, sort of, as long as you don't want any of the export features and without them it's just a toy.

Hmmm... it could be one of the "preferences".I think on Windows they are stored in the registry. You could try to search for JPatch and when you find the jpatch settings, delete the whole branch. Wild guess though...
